Description

Hot water bottle stopper

Technical field

The utility model relates to daily living article field, is specifically related to a kind of hot water bottle stopper.

Background technology

The sealing of traditional thermos bottle mouth is typically employed in bottleneck to arrange interior bottle stopper and arranges outside bottleneck the mode that external bottle cap combines, in the time of falling hot water, needs first to open external bottle cap, extract interior bottle stopper again, this kind of mode trouble of falling water, and hand contacts with interior bottle stopper, is unfavorable for the health of thermos flask, when thermos flask rollover falls down to the ground, thermos flask sealing causes pressure in bottle excessive, it is easy to explodes and splits, poor stability. In order to overcome the shortcoming of these conventional thermal water bottle plugs, a kind of hot water bottle stopper comprising hollow main body and cylindrical body has occurred, this hot water bottle stopper internal cavities is provided with a mobilizable spheroid, cavity bottom is provided with the cancave cambered surface coordinated with spheroid, but this hot water bottle stopper carries out sealing and main body is made by plastic material owing to being only provided with by bottom part body coordinating of cancave cambered surface and spheroid, the laminating of cancave cambered surface and spheroid is not tight, affects the heat retaining property of thermos flask.

Summary of the invention

Technical problem to be solved in the utility model is: the hot water bottle stopper providing a kind of convenience of falling water, sealing and good heat insulating.

The technical scheme in the invention for solving the above technical problem is: a kind of hot water bottle stopper, comprise the lid body being provided with cavity, described lid body bottom be provided with for thermos flask bottle body water-lute and the cylindrical body with thermos flask inner space, described lid body side surface is provided with the water outlet that lid portion inside cavity is in communication with the outside, it is provided with for the sealing mechanism of isolated cavity and thermos flask inner chamber in described cylindrical body, described sealing mechanism comprises and is located in cavity mobilizable spheroid and is fixed on the sealing-ring that cylindrical body inwall makes by resilient material and coordinate with spheroid, described sealing-ring comprises recessed cancave cambered surface, described sealing-ring also comprises the first wear ring being located at cancave cambered surface bottom and extend radially inwardly along sealing-ring, the internal diameter of described first wear ring is less than sphere diameter.

Compared with prior art, the utility model has the advantage of: use hot water bottle stopper time of falling water, tilting thermos flask makes spheroid move out from sealing-ring, can complete down water, and process is convenient, when vertically placing thermos flask, cancave cambered surface holds spheroid, forms body seal, and spheroid continues to press down the first wear ring, first wear ring auxiliary seal, reaches better sealing, heat insulation effect.

Improve as one of the present utility model, described first wear ring bottom is also provided with the 2nd wear ring, the internal diameter of described 2nd wear ring is less than the internal diameter of the first wear ring, by described improvement, when vertically placing thermos flask, spheroid presses down the first wear ring until against the 2nd wear ring, the 2nd further auxiliary seal of wear ring, makes hot water bottle stopper have better sealing, heat insulation effect.

Also having a kind of improvement as of the present utility model, in described lid body, the height of cavity is less than the diameter of spheroid, by described improvement, when tilting thermos flask, spheroid is stuck in cavity after rolling out from sealing-ring, and hot water bottleneck is not opened completely, makes hot water bottle stopper have better heat insulation effect.

A kind of improvement is also had as of the present utility model, described cylindrical body outer wall is sheathed with the blocking cover made of resilient material, described blocking cover periphery is interval with multiple blocking ring extended radially outwardly along blocking cover, described blocking ring and thermos flask inner chamber shrink-fit, by described improvement, hot water bottle stopper coordinates simply with thermos flask inner chamber, multiple blocking ring fitted seal, ensures sealing, the heat-insulating property of hot water bottle stopper.
